Before you begin create the following folder structure:
Main Project Folder
	cex
		data

		outreg
	brfss

	cps

The data subfolder will house the cleaned data for each dataset. The raw subfolder will contain the uncleaned Stata data (as downloaded per below). The outreg folder will contain all regression results for that dataset. 

All data used in this project is publicly accessible.  To acquire the raw data used in this project: 
	1) CPS: Monthly data files are available on the CPS ftp website (https://thedataweb.rm.census.gov/ftp/cps_ftp.html). NBER provides Stata do files and dictionaries in order to convert the raw data files into Stata format. These files are located at: http://www.nber.org/data/cps_basic_progs.html. The paper's do file, below, uses the CPS files converted into Stata format with the NBER do/dct files as inputs. 
	2) BRFSS: Yearly data files provided in SAS transport format at: https://www.cdc.gov/brfss/annual_data/annual_data.htm. The SAS data is then imported into Stata using the fdause command as part of the data cleaning do file. 
	3) CEX: Zipped Stata files of each year's dataset at: https://www.bls.gov/cex/pumd_data.htm#stata
For each dataset place the downloaded data in its respective "raw" subfolder. 

This paper uses two primary do files (master_data_cleaning_restat.do and master_analysis_restat.do). Both of these files are primarily organized in a big loop, where it will perform the same sets of actions (modified by options as necessary) for each of the three datasets used in the paper's analysis. These do files were used for analysis in Stata 14.1. (Our analysis was performed on Windows (server edition), but these do files should be usable across platforms.)  
	master_data_cleaning_restat.do should be run first. This do file creates the cleaned analysis datasets that will be used. It begins by merging any relevant datasets as necessary. Then it proceeds variable-by-variable to recode the raw data to be standard across the three data sets for analysis. 
	
	master_analysis_restat.do takes the cleaned data from above and uses it for analysis. It creates the primary regressions for each outcome variable and their associated adjusted means. The regression and adjusted means are output using outreg into excel files for use in creating tables. It also creates the relevant summary statistics for each dataset. (Therefore this do file is the source for all tables in the paper.) As currently configured (for download) the do file will create the primary estimates used for all tables in the paper. Options are indicated where the user can change things to create the various robustness analyses as well (i.e. the tables that are only in the online appendix). The analysis is conducted in a nested loop, where the nesting is dataset>sub-sample>sets of controls>outcome variables>regression type. This nesting allows for consistency across analyses. The user can set which options are used at each stage, depending on their desired use case.

Two additional do files are used to create figure 1: 
	figure1_make_data_restat.do. Cleans and combines the additional years of CPS data necessary to make figure 1. It requires as inputs the monthly data files, as well as, the NBER provided Stata dictionary files listed above. (This do file needs to be run after master_data_cleaning_restat.do, since it uses the cleaned data from the primary years of the paper as well.) 
	
	figure1_anaylsis_restat.do Runs the regressions necessary to create figure 1, and then creates figure 1.
	
output.zip contains the primary regression results, figure, and summary statistics created by the above two do files. 

Additionally, two standalone do files were used to create appendix figures A.1-A.4 concerning details of the BRFSS data collection, and Appendix tables A.23-A.24, which contain the life satisfaction regressions.

	appendix_brfss_survey_graphs_restat.do creates appendix figures A.1-A.4
	
	appendix_lsatisfaction_restat.do runs the regressions for appendix tables A.23 and A.24. Note this file requires additional BRFSS data from 2005-2008.
